Working in Blackwood
We work right across Blackwood — NP12 — and in neighbouring Gelligaer and Risca.
Blackwood gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Blackwood house has a combi boiler, a loft shower can usually run on mains pressure without a pump. For a loft bathroom in a tank-fed Blackwood home, we work out how the shower will get its pressure before choosing a single fitting.
Water hardness varies across Gwent: some supplies are soft, others moderately hard or hard. A quick wipe of the glass and an easy-clean coating are worth having on a new shower in Blackwood. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- A check of the floor joists where a bath or large shower tray will sit
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
Decisions to make first
Eaves storage
Low cupboards built into the slope behind the WC or basin take clutter out of the room and hide the pipework.
Where the shower goes
Under the ridge or in a dormer, where the full height is. A walk-in shower with a single panel is usually easier to fit to a roof line than a framed enclosure.
Rules that apply in Wales
Wales applies its own Part P, with a wider notifiable list than England, and its own Part F with similar extract rates. Part H covers the new drainage route down from the loft.
